Summary

I produced a port of the OpenVPN to support PocketPC devices as a client. This
activity consisted chiefly of:

Producing a port of the TAP virtual NIC driver.

Accommodating for the lack of many standard runtime routines in the CE
environment.

Producing a 'management' application which provides user-interface to
control VPN connections.

I did this because I wanted it personally, and because there apparently wasn't another
similar effort underway. It is my hope that this might be of use to others
as well. This has not been merged into the official
OpenVPN code base, but that will happen when I get the bug volume low enough to
liberate some time.

I would like to invite anyone interested to download the files, install, and
play with it. There are some known issues, and
I'm quite sure that there are many unknown ones as well! Far be it from me
to delight in bug reports, I am interested in receiving these from the field in
the interest of more rapidly converging on a quality level than I could hope to
achieve operating as an individual developer. I do believe that it is
genuinely usable even despite these limitations -- I've been using it.

I expect that the official openvpn-users mailing list can do with less email
on bug reports related to this port (at least at this
time), so it might be best to contact me directly at: dev@ziggurat29.com.

Scope of Testing Already Done

I have tested the application with an iPaq 4150, running WM2003, and an iPaq
4700 running WM5. There have been other devices tested in the field that
folks individually report on in the forum.

I have tested in a tunneling configuration. I think I have tested in
bridging as well -- I only just recently got bridging set up and I believe
it is working correctly.

I have been happily pushing data over the TAP interface for several weeks now
(I think the day of the first Ping of Joy was March 27th), and I have left a client
pinging through the tunnel for over 24 hours so I feel pretty good about stability. I have
accessed resources on the server though the tunnel, such as web pages, with
client apps like PIE.

The past month has been spend doing bug fixes as problems arise. Details on known pending issues in

Disclaimer

This is early-access code. While every effort has been made to ensure
that this is usable and free of defects, the user acknowledges that he or she
does so entirely at their own risk, and indemnifies the author of any
liability such as but not limited to suitability of purpose, loss
of property, or life, or sanity in conjunction with the use of this software.

Hey, it's alpha code (some emphatically say it's beta code, but I'm
conservative). Do a backup before you install
just-in-case. It only takes a few minutes and worst-come-to-worst you can
hard-reset and restore. I don't think this will ever be necessary -- it
hasn't ever been for me even during development, but then again I don't have
your particular device.
